Summary:

This is an extract of the decennial Public Use Microdata
Sample (PUMS) released by the Bureau of the Census. Because the
complete PUMS files contain several hundred thousand records, ICPSR has
constructed this subset to allow for easier and less costly analysis.
The collection of data at ten year increments allows the user to follow
various age cohorts through the life-cycle. Data include information on
the household and its occupants such as size and value of dwelling,
utility costs, number of people in the household, and their
relationship to the respondent. More detailed information was collected
on the respondent, the head of household, and the spouse, if present.
Variables include education, marital status, occupation and income.

Scope of Study

Universe:
For 1960-1980, all PUMS records for persons 18 and over.
For 1940 and 1950, all sample line records.

Data Type(s):
survey data

Data Collection Notes:

The stratified sample has unequal sampling rates across
strata and requires the use of weights for analyses using more than one
stratum. The epsem sample was selected in a second stage from the
stratified sample and used compensating sampling rates within each
stratum so that the overall probability of selection for each person is
equal. The person level weight for use with the stratified sample and
the household weight to be used with the epsem sample are included in
the data file.

Conducted by the United States Department of Commerce, Bureau of the Census.

Methodology

Sample:
Stratified sample of adults contained in the Public Use
Microdata Sample. Approximately 500 records were drawn from each of 28
sex/age/race strata. Additionally, an equal probability (epsem) sample
was drawn from the stratified sample.

Data Source:
